IMPROVEMENT IN BALE-BAND STRETCHERS.

Specification forming part of Letters Patent No. 185,347, dated December12,1876; application filed October 11, N576.

To all whom it may concern:

Be it known that I, CHARLES M. PEARRE, of the city and county ofGalveston, and State of Texas, have invented a new and ImprovedBale-Band Stretcher; and 1 do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawing, forming part of this specification, in which-Figure l is a perspective view of the baleband stretcher in its openposition. Fig. 2 is a perspective view of the same in its closedposition. Fig. 3 is a view of the device applied to a cotton-bale inboth its open and closed position.

The object of my invention is to provide a convenient and effectivebale-band stretcher to be used in baling cotton, hay, 820., for thepurpose of taking out the slack of the band that cannot be taken out byhand, while the bale is under the press; to which end my inventionconsists in a bar, carrying at its end a griping device for one end ofthe band, and a guide-socket, in combination with an elbow-lever,pivoted at its end to a slide-bar moving through said guide-socket, andcarrying also a griping device for the other end of the band, which twogriping devices are adapted to be brought together by bringing thehandles of the elbow-lever and bar together, and tilting the elbow-leverupon its angle, at which point it is attached to the bar by a keeper,and slides over an inclined portion of the same upon rollers, ashereinafter more fully described.

In the drawing, A B represent the griping devices that hold the bentends of the band, the first of which, A, is located upon the side of theend of bar C, while the second, B, is 10- caled upon the side of thelower end of slidebar X. These griping devices consist of fourprojecting plates or lugs, having three intervening slots, of which thetwo outside slots areintended to receive the bent ends of the band,while the central slot is made deeper than the rest, and is intended toaccommodate the bale-tie, which is slipped into the same, so as toconnect the two bent ends of the band when brought together. D is anelbow-lever, the outer arm of which is pivoted to the top of theslide-bar X, which latter passes through the guide-socket a, formed inthe end of the bar 0 beside the griping device A, so that the twogriping devices A and B are brought together in alignment. The saidelbow-lever isprovided with a keeper or strap, 1), that embraces the bar0, and carries upon opposite sides of said bar friction-rollers c g,which move upon a curved or inclined portioinf, of the bar 0.

In making use of the bale-band stretcher, as thus described, it isapplied to the bale of cotton, as shown in Fig. 3, with the bar 0 atright angles to the side of the bale, and the handle of the elbow-leverI) nearly vertical, in which position the griping devices are farthestapart. The ends of the band are then passed through the outside slots ofthe griping devices, and after being bent around are turned inwardlynext to the bale, and passed through the inside slots, so as to have thefree ends of the band inside, and next to the bale. The handle orelbow-lever is then brought down to bar 0, bringing the griping devicestogether, and tightening the bale-band, while a tie, such as is shown indetail at G, is inserted in the deep central slot of the gripingdevices, and around the bent ends of the band, so as to securely holdthe same after the stretcher is removed.

in bringing the handle of the elbow-lever down it will be seen that itsouter arm rises with the slide-bars X, while its angle moves upon therollers along the incline f of the bar 0 until the arm of theelbow-lever is parallel with the bar X, as shown in Fig. 2; and I amthus enabled to avail myself of the greatest advantages of leverage atthe end of the movement, and at the time when it is most required, theincline eo-operating to give a greater throw to the bar X and gripingdevice at the end of the movement, and an easier movement at the start.

In Fig. 3 four of the hands are shown with the slack all taken out, andthe band secured by means of my improved stretcher, while the restrepresent those in which the slack has been partially taken out by hand,and to which my stretcher is shown applied in both its open and closedposition for completing the tightening and securing ot' the tie.

By means of my improved stretcher I am enabled to take from eight tofourteen inches of slack'out of a band more than can be done by hand,whereby the bale may he reduced in dimension, so as to occupy 211 muchsmaller space.

Having thus described'iny invention; what lclainrasnewisr r l. Thegripers A and"B,-arrenged 'tzo he separated or brought together; and hauing" projectinglngsor plates forming-e central "deep slot for thereception 0fthebale-tie,and

having one arm pivoted to the bar X; and moving at its angle upon har'Oby means of rollers and keepers, substantially as described. 3. The bar0, curved or inclined at f; and
